BACKGROUND Field of Invention

At least one feature pertains to a disposable beverage lid.

Disposable hot beverage containers and suitable lids for these containers are critical supply items for any business serving hot beverages. In order to meet the needs of both the company and the customer, a disposable lid must at least meet the following criteria: the lid must be inexpensive to manufacture, import and/or purchase; the lid must adequately couple to the container; and the lid must be user-friendly to the consumer.

Since disposable lids are generally manufactured for single use, the cost to manufacture is extremely important, especially to those businesses whose principle product is hot beverages (e.g., a coffee shop). At the same time, however, the lid must adequately couple to the container to reduce the chance of the hot beverage spilling and potentially injuring the consumer or causing damage (i.e., stains) to garments worn by the consumer. Additionally, the lid must be user-friendly in manipulation so that the consumer can remove the lid, e.g., add sugar, sugar substitutes, milk, cream, etc., without causing the beverage to spill and user-friendly in use to allow the consumer to drink from the cup (i.e., a drinking port) without removing the lid from the cup.

DETAILED DESCRIPTION

The following detailed description is of the best currently contemplated modes of carrying out the invention. The description is not to be taken in a limiting sense, but is made merely for the purpose of illustrating the general principles of the invention.

Embodiments of the invention are directed to disposable beverage lids which may be used in conjunction with beverage containers. In one embodiment, a disposable beverage lid is generally circular and configured to removeably couple to a beverage container. The lid may include an elevated rim in-set and about the periphery thereof with a dome within a recess defined by the elevated rim. A plurality of apertures may be located within a channel defined by an inner wall of the elevated rim and an outer periphery of the dome.

FIG. 1 is a perspective view of a disposable beverage lid according to an embodiment of the invention. As shown, a disposable beverage lid 100 may be generally circular in shape and configured to removeably couple to a beverage container (not shown). In one embodiment, the lid 100 includes a beverage container coupling portion 102 with a flange 104 extending downwardly therefrom and an elevated rim 106 extending upwardly from an inner periphery of the coupling portion 102. The coupling portion is configured to removeably couple to the bead (or rim) about a periphery of a cup as known by one of ordinary skill in the art. The elevated rim 106 defines a recess 108 in which a dome 110 is located therein. A plurality of apertures 112, or “drinking ports”, may be situated within a channel 114 defined by an outer periphery of the dome 110 and an inner periphery of the elevated rim 106. Materials which comprise the lid 100 include, but are not limited to, polystyrene and polystyrene combined with co-polymers such as polybutadiene, acrylonitrile butadiene styrene, or divinylbenzene. A thickness of the material may be between about 0.005 inches and about 0.020 inches, in one embodiment, about 0.010 inches.

FIG. 2 is a rear view of a disposable beverage lid 200, corresponding to the disposable beverage lid 100 of FIG. 1. FIG. 2 shows beverage container coupling portion 202, flange 204 and elevated rim 206. As shown, flange 202 extends downwardly and is angled in an outwardly direction relative to the coupling portion 202. On the other hand, elevated rim 206 extends upwardly and is angled in an inwardly direction relative to the coupling portion 202. In one embodiment, elevated rim 206 is in-set relative to coupling portion 202. That is, elevated rim 206 extends upwardly beginning from the inner periphery of the coupling portion 202.

FIG. 3 is a front cross-sectional view of a disposable beverage lid 300, corresponding to the disposable beverage lid 100 of FIG. 1 taken along lines 4-4. FIG. 3 shows beverage container coupling portion 302, flange 304, elevated rim 306, recess 308, dome 310 and channel 314. According to this embodiment, elevated rim 306 is doubled-walled with an outer wall angling upwardly and inwardly and an inner wall angling downwardly and inwardly as well. As shown, dome 310 defines a bottom of the recess 308 and is substantially recessed therein. That is, the highest point of the dome 310 is substantially lower relative to the uppermost portion of the elevated rim 306. In further detail, the dome 310 defines a center 318, and at such center 318, a curvature of the dome 310 defines a center tangent line 320. As shown, the channel 314 is parallel to the center tangent line 320. Furthermore, also as shown, a tangent 322 of the curvature of the dome 310 where it joins with the channel 314, i.e., at its outer periphery, is in an angular relationship that is offset to the channel 314. The beverage coupling portion defines a first reverse bottom-facing surface 324 that is configured to mate with a lip of the beverage container. The elevated rim 306 defines a second reverse bottom-facing surface 326 that is open to the beverage container when mated thereto. The first reverse bottom-facing surface 324 and the second reverse bottom-facing surface 326 may also partly define respective grooves 334, 336. With simultaneous reference to FIGS. 1 and 3, the disposable beverage lid 100, 300 may also be described in terms of the channel 114, 314 being defined by a first annular boundary segment 140, 340 that corresponds to an inner periphery of the elevated rim 106, 306, as well as by a second annular boundary segment 142, 342 that corresponds to the an outer periphery of the dome 110, 310. As shown, the channel 314 is oblique relative to the curvature of the dome 310 and the wall of the elevated rim 306.

FIG. 4 is a top aerial view of a disposable beverage lid 400, corresponding to the disposable beverage lid 100 of FIG. 1. FIG. 4 shows beverage container coupling portion 402, flange 404, elevated rim 406, recess 408, dome 410, channel 414 and the plurality of apertures 412. In one embodiment, the plurality of apertures 412 may be symmetrically spaced within the channel 414 and adjacent the inner periphery of the elevated rim 406. In other embodiments, the plurality of apertures may be bunched together, or aggregated in a group, in one or more locations within the channel (not shown). Utilizing the view shown in FIG. 4, for example, there may be a first group of aggregated apertures 412 a, and a different second group of aggregated apertures 412 b. The plurality of apertures 412 may number from two (2) to forty-five (45), in one embodiment, thirty-two (32). According to embodiments of the invention, the plurality of apertures 412 may be approximately circular, oblong or any other suitable geometric shape; however, in any embodiment, the plurality of apertures 412 should collectively or singly allow a volume of liquid to pass through when coupled to a beverage cup (not shown) and when a consumer is drinking from the cup. That is, the plurality of apertures 412 provide a metered flow of liquid when the lid 400 is coupled to a disposable cup and tilted relative to a horizontal plane. Each aperture may be between about 0.025 inches and about 0.100 inches in width, in one embodiment, about 0.050 inches in width.

FIG. 5 is a side view of a disposable beverage lid 500, corresponding to the disposable beverage lid 100 of FIG. 1. FIG. 5 shows beverage container coupling portion 502, flange 504 and elevated rim 506.

FIG. 6 is a bottom aerial view of a disposable beverage lid 600, corresponding to the disposable beverage lid 100 of FIG. 1. FIG. 6 shows beverage container coupling portion 602, flange 604, elevated rim 606, recess 608, dome 610, channel 614 and the plurality of apertures 612.

One conventional beverage lid includes a drinking port on a peripheral rim of the lid. When the cup coupled to the beverage lid is subjected to motion, i.e., when a consumer is walking or when the cup is in a cup holder in a car, liquid has a tendency to spill out of the drinking port. Moreover, this type of lid often includes additional openings for heat ventilation (in the case when the liquid is hot). These additional openings can also be sources of spillage. A solution is to temporarily cap the drinking port with a so-called “splash stick”, however, this solution is not user-friendly as it does not allow the consumer to drink the beverage without removing the “splash stick” and does not completely prevent spillage. Moreover, this solution does not address spillage from the heat ventilation openings.

Another conventional beverage lid includes a “living hinge” which can partially cap the drinking port. Again, this type of lid often includes additional openings for heat ventilation (in the case when the liquid is hot). This solution is not user-friendly as it does not always function properly and does not completely prevent spillage. For example, a defective hinge may be removed by the consumer thereby defeating the purpose of the hinge (i.e., to prevent spillage). Again, this solution does not address spillage from the heat ventilation openings.

The beverage lid as described previously according to embodiments of the invention has advantages over conventional lids. For example, the lid's specific geometry, i.e., the dome within the recess defined by the elevated rim and the plurality of apertures (drinking ports) within the channel, substantially or completely prevents the fluid from spillage while dynamic, i.e., while moving (sloshed around). More particularly, because the drinking ports are not on the rim but rather distanced from the edge of the lid, i.e., on the interior of the elevated rim, spillage is substantially or completely eliminated. The elevated rim functions as a barrier to prevent or substantially prevent liquid from spilling over. Moreover, the dome within the recess defined by the elevated rim forces the liquid to stay in the channel if there is any residual liquid once the consumer takes a drink.

Additionally, because there are numerous drinking ports, the need for additional openings to vent the lid is eliminated. That is, the sizing and spacing of the drinking ports simultaneously function as drinking ports and heat ventilation openings. Moreover, the sizing and spacing of the drinking ports provide a metered flow of fluid completely controlled by the consumer. Additionally, the lid according to embodiments of the invention allows for the consumer to drink from any edge. Additionally, heat transfer properties attributable to a lower volume of space between the lid and the hot fluid show an unexpected result that the liquid stays hot longer when compared to conventional lids.

While certain exemplary embodiments have been described and shown in the accompanying drawings, it is to be understood that such embodiments are merely illustrative of and not restrictive on the broad invention, and that this invention is not to be limited to the specific constructions and arrangements shown and described, since various other modifications may occur to those ordinarily skilled in the art.
